Several safety measures protect service technicians and homeowners from eye or skin UV exposure, including a lamp shutoff switch, and a sight glass for safe and easy lamp inspection. A protective cover with a safety interlock switch immediately deactivates the lamp before the service technician or homeowner can access or service the unit. The effectiveness of germicidal UV-C is limited once molds, which are more resistant to UV energy than airborne bacteria, have already formed on surfaces.

Yes, the fabric provides a complete block from UV rays. Our optional items, our Solar Shield and "Weather Wrap?", will provide the same protection for the screen runs. See similar questions...

Clothing must have a UPF (Ultraviolet Protection Factor) of at least 15 to be considered sun protective. A typical t-shirt has a UPF of 7 (Source: Morehouse School of Medicine). Splashskins are UPF 30 or above (blocking out 96-98% of the sun's damaging rays). Learn More! See similar questions...

Ultraviolet (UV) rays are located just past the violet portion of the visible light spectrum; sunlight is the main source. UV light is broken into three different types: UVA, UVB and UVC. UVA has longer wavelengths and passes through glass easily; experts disagree about whether or not UVA damages the eyes. UVB rays are the most dangerous, making sunglasses and sunscreen a must; they don't go through glass. UVC rays do not reach the Earth because its atmosphere blocks them. See similar questions...

Most people think that they're only at risk when they're outside on a sunny day, but UV light can go right through clouds, so it doesn't matter if the sky is overcast. The sun's rays are strongest between 10 am and 2 pm. Glare and reflections can give you trouble, so have your sunglasses ready if you'll be around snow, water or sand, or if you'll be driving (windshields are a big glare source).

No, our equipment is state of the art and minimizes patient exposure. We use the most advanced digital X-ray technique. The office follows ADA guidelines as to the frequency of radiographs. X-rays are never automatically taken, the decision is based upon clinical experience. All our units have filters and we use the fastest film speed possible. Additionally, you will be covered with a lead apron decreasing your exposure to negligible levels. See similar questions...

CAP UV-C and UV Plus products are equipped with high quality, high-output U.S.-made lamps for optimum performance and reliability. The hard quartz lamps are rated for at least 9,000 hours (1 year) when installed and used in accordance with the operating manual. Lamps may last much longer in some situations, but annual lamp replacement is recommended since the UV output of any lamp typically starts to drop off after about 9,000 hours. On/off lamp cycling will reduce lamp life. See similar questions...

The UV rays emitted by indoor tanning lamps do not emit sufficient energy to penetrate past the skin layers. Thus, despite claims and rumors to the contrary, internal organs are not directly impacted by longer wave UV light. See similar questions...

Caviseal will burn over and change color as well as lose a 1/16 of an inch in the first month. After it burns over the degradation action slows and you will lose about an 1/8" in four months. However we want it to burn over some because it creates a hardened shell on the face increasing its permeability and moisture penetration characteristics. Back to Top See similar questions...

No. The risks are approximately equal. For some time it was hoped that UV lamps could be made safer by making more use of long-wavelength (UV-A) radiation. That type of radiation is much less carcinogenic than the shorter-wavelength UV-B radiation, but one needs more UV-A than UV-B for acquiring a tan. See similar questions...

It's very common for customers to think our UV lamps are not efficient like competitors because they are low priced, but the fact is they are more powerful than most UV-C germicidal lamp products used in other UV air purifier systems. Plain and simple, we don't mark them up. You can find our same style lamp used in our UV air purifier at a competitor site for $45 each, and we even found another for $107 each, that's just ridiculous. The $22. See similar questions...

Yes. People with cataracts (or who've had cataract surgery), macular degeneration, and retinal dystrophies should be extra careful. Read more about these conditions in our Eye Problems and Diseases section. See similar questions...

You never want to expose your skin or eyes to the light from a UV system. UV light is non-visible however it can be harmful, similar to the harmful effects of UV light from the sun. UV lamps can actually cause a severe sunburn-like effect if skin is exposed for long periods of time. Always ensure that you are wearing some type of protective glasses (ie. Safety glasses or sunglasses) when working on a UV system and the lamp is exposed. See similar questions...

In tests that do use ionizing radiation, the dose is usually very small, and is often similar to what you would get from natural background radiation in everyday life. As an example, a dose for a typical X-ray procedure might be 30 - 1,000 mr. Despite extensive study of the effects of radiation, direct evidence does not show that these doses are harmful to humans.

Generally, the shorter the wavelength, the more biologically damaging UV radiation can be if it reaches the Earth in sufficient quantity. UV-A, although it is the least energetic form of UV radiation, reaches the Earth in greatest quantity. Most UV-A rays pass right through the ozone layer. UV-B radiation is potentially very harmful. Fortunately, most of the sun's UV-B radiation is absorbed by ozone in the stratosphere. See similar questions...
